So this is a strange problem...I'm getting the Following error when try to
view the list mode of my court_detals object in the Admin interface.
OperationalError at /admin/contrack/court_details/
(1109, "Unknown table 'contrack_locations' in order clause")
Request Method: GET
Request URL:http://localhost:8000/admin/contrack/court_details/
Exception Type: OperationalError
Exception Value:(1109, "Unknown table 'contrack_locations' in
order clause")
Exception Location:
/usr/lib/python2.4/site-packages/MySQLdb/connections.py in
defaulterrorhandler, line 32

I think the whatever constructs the SQL interface is doing something
wrong..
Below is the output of the SQL it tries to contstruct..
BTW,I've tried running the SQL manually, and it too tells me that it is
wrong.
I think that it has something to do with it leaving out the
contrack_locations in the query it constructs.
Also below you will find my classes for the query in question.
This is on a fresh init of the whole app (init, install admin, install
contrack)
